THE CINDERELLA WASHING MACHINE COMPANY, OF CLEVELAND, OHIO, A GOR- POBATION OF OHIO wnsnme mcnmn Original No. 1,824,481, dated April 12, 1927, Serial tor reissue filed April 10,

This specification is an amended specification of United States Letters Patent'No. 1,624,461 of April 12, 1927, issued for the same invention.

This invention relates to improvements in machines ,for washing dishes and other articles, such as clothes.

The objects of this invention are to provide a washing machine in which dishes or other articles can be washed, rinsed and dried, with means for agitating the water during the washing operation and for circulating a current of air over the dishes or other articles for drying the same; to provide means whereby the heat and steam from the wash water may be conserved during the washing and rinsing operations and fresh air circulated and renewed during the drying operation; to provide a detachable deflector cap for determining the source and cha-racter'of the air forced through the machine; .to

'ing for e ecting circulation ofair' through the machine together with means for pro- 2 tecting the same from the water in the easing; to provide an improved sectional casing and" a removable rack to permit convenient shipping and assembly of the same-as well as loading and unloading when in actual use; and to provide an improved rack structure and means for supporting the same within the casing, for use in washing dishes and analogous articles,- However, the machine may be used for washing articles other than dishes, with or without a rack suitable for supporting such other articles.

Other objects of the invention will be apparent from the following description and claims when considered together with the accompanying drawings, which illustrate my invention as applied to a machine for washing dishes.

Figure 1 is a top lan view of my improved washing machine; Figure 2 is a side elevation; Figure 3 is a vertical transverse section; Figure 4 is a vertical longitudinal section; Figure 5 is a plan view of the lower half of the device; and Figure 6 is an inverted plan view of the upper part of the device.

rovide a fan in the machine cas- No. 523,117, filed December 17, 1921. Application 1929. Serial in. 354,118.

The casing in the present device comprises the substantially elliptical members 1 and 2 which are seated one upon the other by means of the flange 3 depending from the upper member into the correspondingly formed channel 4 around the lower member. The rubber gasket 3 forms an air-tight joint and the particular shape of easing adapts it to seat in the ordinary kitchen sink or on the drain board. The lower member is'provided with a rack for holding the dishes or other articles while the upper member is provided with a motordriven fan, preferably a suction fan, for efi'ecting circulation of vapor-or air through the water in the lower member during the washing operation, as well as during the rinsing operation if so desired, and later for effecting circulation of outside air over the dishes or other iHtlCleS for drying the same, as will appear ater.

The rack shown in the drawing is designed especially to support dishes in the lower member and comprises a wire frame 5 of the form and structure as here illustrated, this frame being covered with rubber by dipping the same into a rubber composition. This rack, as viewed in Figure 3, comprises the marginal strands 7, the intermediate strands 8, and a plurality of transversely extending strands 9 of a configuration between the marginal and intermediate strands resembling an inverted V, indicated at 9. The middle portions of the transverse strands are substantially horizontal as indicated at 10. This rack is supported upon the trough member 12 which in turn is suitably secured upon the upstanding projections 13 which are cast integrally at the bottom of the lower casing member 1, these members forming a passage 13a. The trough member is notched, as indicated at 15, for the seating of the lower transverse portions of the rack, as clearly indicated in Figures 3 and 4.

In the bottom of the. trough member, which is open entirely throughout its top, is provided the comparatively restricted. slot 16 for passage therethrough of the vapor or air WlllCh is set in circulation by thesuction fan. One of the upstanding projections 13 0 is also provided with an opening 17 forming part of the passage for the vapor or air which is forced through the opening 16. The vapor or air is forced through a condu t which is formed by complementary conduit sections provided in the upper and lower casing members and which are adapted for registry with each other upon assembly of the upper and lower parts of the casing. The lower conduit is indicated at 18 while the conduit in the upper casing member is indicated at 19; and it will be noted that the lower conduit has communication through the opening 17 with the passage 13a formed by the trough member 12 and the upstanding projections 13. It is noted also that the rack is provided with suitably formed offsets 7 about the two sides of the conduit 18 so that the conduit in the lower casing member will not interfere with the seating of the rack.

The upper casing member 2 is provided with an opening 20 through the top thereof which is closed by means of an electric motor 21 whose base is secured in any suitable manner over the opening 20, the motor resting.

upon the top of the casing. A fan 22 is fixed to the rotor shaft of the motor 21 and located in the top part of the casing portion 2. An integrally formed auxiliary casing member 23 surrounds the fan, is of a substantially convolute form, and also in combination with the top of the casing member 2 forms the conduit 24 which has communication with the conduit 19. A circular guard plate 25 is secured by means of bolts 26 and spacers 27 in spaced relation to the under face of the auxiliary casing member 23, the purpose of this guard plate 25 being to protect the fan from the water in the lower part of the casing. The plate 25 is perforated, however, as indicated at 28, so as to permit the passage of vapor or air therethrough as it is sucked by the fan up through the casing. The bottom of the auxiliary casing 23 is provided with the circular opening 29. The perforations in the plate 25 also permit the draining of any water that might be splashed thereonto.

On one side and at the upper corner portion of the upper part of the casing I have provided the detachable deflector cap 30 which is secured in position on the casing by means of the bail 31-pivoted to the casing member at 32 and adapted to engage over the projection 33 provided on the cap. This dellector cap 30 is formed with an upper flanged opening 35 leading to atmosphere, the cap 30 forming an intermediate part of the conduit which comprises the conduit sections 24 and 19, so that when the deflector cap is secured in position, as shown in Figure 3, continuous passage is provided for the vapor or air. This deflector cap is secured in such position during the washing operation as well as the rinsing operation, if so desired, so that the warm air and steam from the water in the casing will be sucked up by the fan and discharged therefrom into the duct 24. Atmospheric pressure through the opening 35 causes this vapor and steam to be forced through the ducts 24:, 19 and 18, rather than out through the opening 35, and thence up through the wash water, a vacuum having beenrrcated above the wash water by the fan. Thus the heat of the water is conserved. Vhen, however, it is desired to dry the dishes, the deflector cap is removed so that outside, comparatively dry air will by virtue of its atmospheric pressure pass through the duct 19, which is now open to the atmosphere, and be drawn up through the casing by the vacuum created by the fan; while the air after being used will be discharged from the duct 24 to the outside atmosphere. The opening 35 may be used also as a means of filling the casing with water to the level indicated in Figure 4, or it can be filled by attaching a discharge tube conncctcd at one end to outlet 36 and at its other end to a source at sufficient elevation.

For operating the machine to wash dishes, the latter are placed upon the rack in the manner indicated in broken lines in Figure 3, the plates resting upon the intermediate strands 8 between the strands 9. Water is then supplied to the casing to the proper level. With the deflector cap 30 secured in position, the warm air and steam will be sucked up by the fan, thereby creating a vacuum above the water, the atmospheric pressure through opening 35 causing circulation 10 of such vapor through the casing so as to cause agitation and aeration of the water. The opening 35 maintains the pressure in the duct 19 substantially at atmospheric. The passage of air up through the restricted slot 16 in the bottom of the trough member 12 forces the water up out of the trough, whereupon the water from the sides of the casing rushes in to again fill the trough. Thus the water is swished from side to side and is spurted intermittently upwardly as the trough is alternately emptied and filled. Upon comple. ion of the washing operation the wash water is drained through the discharge outlet 36, provided with a suitable closure 37. Running of the fan during the draining operation will continue to agitate the water until it is all discharged, and thus the grease and dirt suspended in the water is prevented from depositing in the casing. The dishes are then rinsed, with or without the fan, preparatory to drying. In order to circulate fresh and comparatively dry air over the dishes, the deflector cap 30 is removed so that outside air is drawn into the ducts 19 and 18, this air being discharged horizontally through the conduit 24.

It is clear that this machine may be used for washing articles other than dishes, either with or without a rack, and that, when using ticlcs to be washed by such machine or appliance, and the following claims where the context permits are intended to be construed accordingly.
